SuSE 10.3 with Microsoft Natural Keyboard 4000 doesn't work



Hi group,

I have a strange problem with my new keyboard and I can't solve it.
I would like to work with the F-keys but they doesn't act right. There
is no response when I press any F-key .
When I run "xev" and press F1 I get the following:

#####################################################################
KeyPress event, serial 31, synthetic NO, window 0x3800001,

state 0x0, keycode 245 (keysym 0x0, NoSymbol), same_screen YES,
XLookupString gives 0 bytes:

and also for F2 I got
#####################################################################

Please what can I do to activate these keys ?
